raar .Leraren CAP.

Application med INovember To all trimm if may concern Be it known that l. (iRoveu (liArrLE, a citizen of the l'nited States. residing at Greensboro, in the county of (luilford and State of North tarolina. have invented new and useful Alfrnprovements in Caps. of which the following is a specification.

This` invention lrelates to a cap for radiators of internal combustion engines..the general object of the invention beingY to facilitate filling of the radiator and also to prevent loss. b v theft or otherwise of the cap.

Another object of the invention is to pro-Y vide means whereby a motor meter can be 'attaelied to the rap when desired.

Thisv invention also eonsists in certain other features ot' construction and in the combination and arrangement of the several parts. to be hereinafterfully described, illustrated in the aeconipanying` drawings and speeifieally pointed out inthe, appended elaini.

ln describing my invention in detail, refr erenee will he had to the accompanying wherein like characters denote like or eorresponding parts throughout the several views. and in which Figure 1 is a plan view of a cap' con# strueted 1n accordance with my invention.

Figure Q is a longitudinal section thereof.v

with the parts separated.

Figure. I3 is a horizontal sectional view. ln these views 1 indieatesthe lower part ol the eap and 2 the upper part thereof. The v lower part is provided with the Screw threaded lower end 3 for engaging the filling spout of the radiator. This lower part is of substantially bowl-shape and is provided with the inwardly extending lugs 4 adjaeent its upper end. `The part i2VV is formed of the stem 5 ha'ving the head yt3 thereon and the. part, 7 whieh engages the stem and is held thereon hvthe nut. 8. 4This part 7 is provided with the annular flange f) which is adapted to fit in the'upper end of part 1. A spring 10 has one end eon. neeted with a spider l1 in the part 1 and its upper end Connected with the lower end of vthe stem 5 so' tzhatuthe, parts 1 and 2 are conneeted together in a flexible manner, by said spring. This spring is sufliciently flexible to permit the part 2 to be lifted off 29, 1921. semina. sisma.

the part 1 so that the radiator can be Filled hy pouring water into the part. l. When in normal position, however, the spring will hold the part '2 upon the part 1. l also prolvide means for locking the part 2 upon the part 1, such means consisting of the springv )ars/12 on the stem which engage recesses l in the. lugs 4.1he lugs being beveled upon their lower faees to d'ireet the ends of the spring hars 12 into said recesses when the part 2 is turned to plaee the bars 12 inV engagement with the lugs.

By removing the nut 8 the part 7 may' be taken ott' the stem and a motor meter or the like substituted.

From the above it. will be seen that my in` .rentiokn will facilitate the filling of the radiator as theipper part of the eap can be quickly and easily removed from the lower part to permit water to be poured into the lower part.- The spring. however., holds the upper part in connection with the lower part so that. there is no danger of the said upper part being lost. through failure to replace it, or of being stolen.

It is thought from the foregoing description that the advantages and novel features of my invention will he readily apparent.

I desire it to be understood that le may make changes in the construction and in the eombination and arrangement of the several 'asY parts, provided that sueh changes tall within the scope ot' the appended claim.
